METHOD OF PRODUCING IMPRESSIONALISTIC ORNAMENTAL SURFACES.

No Drawing.

To all whom it may concern:

Be it known that I, MARSHALL A. TURNER. a subject of the King of Great Britain, and a. resident of the city of Peterborough, in the county of Peterborough, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Methods of Producing Impressionalistic Ornamental Surfaces, of which the following is the specification.

My invention relates to improvements in methods of producing impressionalistic ornamental surfaces and the object of the invention is to devise means for imparting to the finished plane surface the appearance of being embossed or in relief.

In carrying out my invention I first apply to the surface to be finished a coating of viscous or gummy liquid, such as a solution of cornstarch or other material which will have the property of coalescing in so far as the different portions of the coating are concerned to constitute a coating of uneven thickness. It is immaterial what method is employed to coat the surface as the coating may be stippled on, brushed on, or the material to be treated may, if convenient, be dipped into a bath of the coating.

The wet coated surface is now rugose, having innumerable mounds and indentations caused by the uneven running of the coating.

I now apply colouring pigment in liquid form to the coating either by spraying it on, dipping the material into such liquid or otherwise applying it thereto. However I preferably apply the pigment to the wet coated surface by means of an air brush which projects it thereonto in the form of a very fine spray or mist, being applied in a direction almost parallel to the plane of the material. The particles of the spray collect on the mounds and the slopes thereof nearest the sprayer or air brush, the sides of the mound remote therefrom being left free, or

almost free from the pigment, thus giving a variation of tone.

The coated and coloured surfaces are now permitted to dry wherein the coating possesses the additional property of drying substantially flat, so that the raised portions and indentations disappear in fact, yet the appearance of the surface is still as if embossed, giving a very pleasing effect. As above described the resultant finished surface while exceedingly ornamental is indefinite in design, but by the use of pattern plates or rolls, definite conventional designs or lettering may be produced.

While my method is particularly applicable to the ornamentation of paper and cardboard surfaces, it is apparent that it could with equal facility be used for decorating walls, ceilings, as well as for ornamenting fabric and textiles of certain types and also for many other uses.

What I claim as my invention is:

1. A method of ornamenting surfaces which consists in applying a coating of cornstarch mixed with sufficient liquid to make it of a viscous consistency whereby such coating is of varying thickness, applying a colouring pigment to the coating while still in the viscous state wherein upon the liquid being evaporated out of the cornstarch the coating will dry substantially fiat on the surface treated while presenting the appearance of being embossed.

2. A method of ornamenting surfaces which consists in applying to the surface a coating of cornstarch mixed with sufficient liquid to make it of viscous consistency, impressing a pattern producing medium into the coating while the cornstarch is in the viscous condition and subsequently applying a colouring pigment to the patterned coating while it is still viscous.
